As one of the most consumed chemical reagents, ammonia (NH3) has a wide range applications in many fields. The demand for may continue to increase with advancement technology and acceleration industrialization. traditional high energy consumption pollution synthesis methods (Haber-Bosch) need be optimized improved reduce environmental dependence. In this work, series Z-scheme NM/Ag@AgCl heterojunctions were prepared as catalysts research photocatalytic nitrogen fixation. By in-situ photodeposition, Ag@AgCl was uniformly distributed on NM surface, interfaces different substances tightly bonded. SPR effect that generated by Ag nanoparticles significantly enhanced light absorption performance heterojunction materials. ESR spectra, signal peak intensity higher than under condition. Constructing beneficial formation Ti3+. strong built-in electric field among AgCl promoted generation heterojunction. had sufficient redox potential overcome thermodynamic barriers drive catalytic reaction. Without adding any sacrificial reagent, production NM/Ag@AgCl-3 reached 76.7 µmol g−1 h−1 full spectrum radiation. rate almost seven times NM. synergistic between photogenerated carrier separation path. This work provided new vision practical application efficient N2 reduction.
